About This Project
After conquering the Great Lakes, what will the invasive Round Goby do to fish in our streams? Four years ago, a local dam being removed provided a clear time to start surveying. The opportunity was recognized, but funds for this spring were stopped by budget changes. We have seen the goby move 23 km upstream and Johnny Darter numbers drop 90%. Longitudinal data may indicate if the young fish are disappearing. The goby is now nearing the headwaters.
